Research ArticleOpen accessIn the abstractAn Investigation of the Effect of Aspect Ratio on the Airfoil PerformanceM. Kopaç, M. Yılmaz, T. GültopThe effect of aspect ratio on the airfoil performance is investigated for airflow about axially symetric wings as a function of the angle of attack. The magnitudes of aerodynamic forces and moments on airfoils resulting from the incompressible viscous flow fields are determined experimentally. The TE54 wind tunnel used for the experiments is an open conduit and has a 300x300 … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,682 accessesView PDFCite
